The process plant employs a conventional heap leach process and has a production capacity of 4.0Mtpa of oxide and transition ore. The ore is crushed in two crushing circuits, agglomerated and transported to the leach pad where it is stacked in two 10m lifts and treated with dilute cyanide solution.
Process Involved In The Extraction Of Gold. Processing Smelting And Refining Gold World Gold Council . The Miller process uses gaseous chlorine to extract impurities when gold is at melting point impurities separate into a layer on the surface of the molten purified gold The Miller process is rapid and simple but it produces gold of only about 995 percent purity The Wohlwill process
The flotation process, which is versatile, can separate minerals as large as 3.3 millimeters 6 mesh and as small as 5 microns and can handle minerals with a specific gravity as high as 19 gold and as low as 1.5 vermiculite. The process can be used in a medium of almost pure water, seawater or

A stamp mill consists of a set of heavy steel ironshod wood in some cases stamps, loosely held vertically in a frame, in which the stamps can slide up and down. They are lifted by cams on a horizontal rotating shaft.As the cam moves from under the stamp, the stamp falls onto the ore below, crushing the rock, and the lifting process is repeated ...
Electrowinning. Gold ore tailing processing plants should be started with the feeder and it will take the extracted materials uniformly to the crusher for the first process. This process is used for resize and pulverize the gold ores into smaller than particles. For secondary crushing, conveyor will take these materials into the cone crusher.
